cgpCaVEManPostProcessing is used to apply filtering on raw VCF calls generated using CaVEMan.
For details of the underlying algorithm please see the CaVEMan site.

cgpCaVEManPostProcessing is available as a separate docker image on quay.io.
And as part of pre-built full analysis images on quay.io.
- dockstore-cgpwxs
- Contains tools specific to WXS analysis.
- dockstore-cgpwgs
- Contains additional tools for WGS analysis.
These were primarily designed for use with dockstore.org but can be used as normal containers.
More detailed instructions can be found on the wiki
As of version 1.10.0 cgpCaVEManPostProcessing has new WXS flags available that are not used by default. These were developed in conjunction with the Dermatlas project and caution is advised when using them.
- cavemanMatchNormalProportionFlag
- withinGapRangeFlag
Full flag definitions can be found here
Flags can be tuned by modifying their parameters in the species ini file. Human example is here. The parameter names correspond to names in the flag descriptions. Further details of flags and parameters are available in the wiki.
Flag/Post Process CaVEMan files.
cgpFlagCaVEMan.pl [-h] -f vcfToFlag.vcf -o flaggedVCF.vcf -c
configFile.yaml -s human -t pulldown -v vcfFlagNames.ini -n norm.bam -m
tum.bam [-u unmatchedStore.tmp]
General Options:
--help (-h) Brief documentation
--version (-version) Output the version number and exit
--input (-i) The VCF input file to flag.
--outFile (-o) The VCF output file to write.
--species (-s) Species associated with this vcf file to use.
--species-assembly (-sa) Species assembly for (output in VCF)
--tumBam (-m) Tumour bam file
--normBam (-n) Normal bam file
--bedFileLoc (-b) Path to a folder containing the centromeric, snp, hi sequence depth,
and simple repeat sorted (gzipped and tabixed) bed files (if required) i.e. the non annotation bed files.
Names of files will be taken from the config file.
--indelBed (-g) A bed file containing germline indels to filter on
--unmatchedVCFLoc (-umv) Path to a directory containing the unmatched VCF normal files listed in the
config file or unmatchedNormal.bed.gz (bed file is used in preference).
--annoBedLoc (-ab) Path to bed files containing annotatable regions and coding regions.
--reference (-ref) Reference index (fai) file corresponding to the mapping of the data being processed.
(must have corresponding fasta file co-located)
--index (-idx) Index of the job (to override LSB_JOBINDEX as used on LSF farms)
--verbose
OPTIONAL:
--sampleToIgnoreInUnmatched (-sp) Unmatched normal to ignore (to be used if the sample is one of those with a normal in the panel).
--processid (-p) Id anaylsis process to be added at a CGP specific header.
--flagConfig (-c) Config ini file to use for flag list and settings.
--flagToVcfConfig (-v) Config::Inifiles style config file containing VCF flag code to flag name conversions see
../config/flag.to.vcf.convert.ini for example
--studyType (-t) Study type, used to decide parameters in file (genome|genomic|WGS|pulldown|exome|WXS|followup|AMPLICON|targeted|RNA_seq).
Examples:
cgpFlagCaVEMan.pl [-h] -f vcfToFlag.vcf -o flaggedVCF.vcf -c configFile.ini -s human -t pulldownConvert old .ini file to .yaml format.
cavemanPostProcessing_ini_to_yaml.pl [-h] -f flag_config.ini -o flag_config.yml
General Options:
--help (-h) Brief documentation
--version (-version) Output the version number and exit
--input (-i) The VCF input file to flag.
--outfile (-o) The VCF output file to write.
Examples:
cavemanPostProcessing_ini_to_yaml.pl [-h] -f flag_config.ini -o flag_config.ymlPlease ensure the following packages are available. Alternatively use the Docker image.
- cgpVcf
- Bio::DB::HTS
- If you have an install of PCAP-core this is already available
Once complete please run:
./setup.sh /some/install/locationsetup.sh will also install bedtools for you.
- Commit/push all relevant changes.
- Pull a clean version of the repo and use this for the following steps.
- Update
lib/Sanger/CGP/CavemanPostProcessor.pmto the correct version. - Update
CHANGES.md - Run
./prerelease.sh - Check all tests and coverage reports are acceptable.
- Commit the updated docs tree and updated module/version.
- Push commits.
